Hire the Best Serverless Developers

I design, strategize, and develop systems that become reliable custom software for business owners and founders—the tools your company runs on and the products you want in market. Before code, we clarify what the software must achieve: who uses it, what replaces manual work or spreadsheets, and what “live” means for your timeline. Then I deliver end-to-end: structure, workflows, data, cloud hosting, integrations, and AI only where it clearly helps—so you get something people actually use, not a technical demo that falls apart under real load. What I build: 1. Custom software for your business — portals, internal platforms, workflows, reporting, intake, quoting, scheduling-style tools 2. New products from your idea — from first version to launch and the releases that follow 3. Complete systems behind your UI — including teams using Lovable or similar who need the full product built properly How I work: 1. Design — map the process and user journey in business terms 2. Strategize — scope v1 vs later phases so budget and timeline stay honest 3. Develop — production delivery on proven cloud and engineering practice, with integrations planned so growth doesn’t force a rewrite What I help with: 1. AWS serverless AI systems Design and build AI-enabled products on Lambda, API Gateway, S3, DynamoDB, SQS, EventBridge, SES, CloudWatch, and OpenSearch—reliable under real traffic, not prototype-only setups. 2. AI chatbots & AI agents End-to-end systems for chatbots, agent workflows, retrieval-based answers, multi-step automations, conversation pipelines, and tool-calling—connected to your product so support and internal teams can trust them. 3. TypeScript & Node.js development Scalable APIs, business logic, auth, and integrations using TypeScript, Node.js, and NestJS—structured so your team or future developers can maintain and extend the codebase. 4. RAG & AI integrations Connect OpenAI, Claude, LangChain, vector search, document pipelines, retrieval, and orchestration into production—quotes, inquiries, knowledge bases, and document-heavy workflows included. 5. API integrations & auth OAuth, OpenID Connect, Cognito, Bullhorn, webhooks, and third-party APIs—implemented securely and in layers that don’t trap core logic inside one vendor. 6. MVPs and AI products Ship a credible first version fast, with architecture that still supports growth after launch—so v1 isn’t thrown away when you add users or features. My core strengths 🔹 AWS Serverless: Lambda, API Gateway, DynamoDB, S3, EventBridge, SQS, SES, CloudWatch, Cognito 🔹 Backend: TypeScript, Node.js, NestJS, REST APIs, backend architecture, workflow systems 🔹 AI systems: LangChain, OpenAI, Claude, chatbot backends, agent workflows, RAG support 🔹 Search & data: OpenSearch, PostgreSQL, Supabase, vector-ready retrieval patterns, document flows 🔹 Infra & delivery: Docker, Kubernetes, AWS deployments, monitoring, CI/CD, scalable cloud architecture 🔹 Integrations: OAuth, OIDC, webhooks, external APIs, secure service-to-service communication The kind of work I’m best suited for 🔹 AWS serverless AI products 🔹 AI chatbot and AI agent backends 🔹 TypeScript / Node.js systems with AI features (full product, not orphan APIs) 🔹 RAG-enabled tools and document workflows 🔹 Scheduling, automation, and workflow platforms 🔹 API-heavy SaaS that needs dependable architecture 🔹 Custom business software for founders and owners 🔹 Teams that need strong product delivery and AI integrations in one partner If you’re a founder or owner with a process to digitize or a product to launch, send a short note: what you need built, who it’s for, and when you want it live.

My specialty and proven track record is enabling founders to go from idea to production rapidly using an AI-driven, agentic software development process built around the following AI-centric pipeline: Discovery → AI Transcription → AI-Optimized Spec → Test-first Development → AI and Human Code Review → Iterative Delivery → Production Claude Cowork was written in 10 days utilizing this process. My background: I’m a US based Fractional CTO & Software Architect with 20+ years of experience leading startups to funding. This combined with extensive experience leading mission-critical initiatives at large organizations like The Federal Reserve and Fannie Mae. I work best with founders who want to move fast, stay lean, and get to a real, working product without unnecessary complexity. Let's build something great.

I help engineering teams and technical founders make the right system decisions before they become expensive — scoping what to build, de-risking architecture before irreversible choices are made, and owning delivery through to scale. My background spans cloud architecture, solution architecture, and database systems across AWS and Azure. The combination matters: most production failures I have seen trace back not to bad code, but to structural decisions made early in the schema, the system boundaries, or the deployment model — that compounded quietly until they could not be undone. I am based in Armenia and work async-first with clients across the US, Europe, and Australia. Architecture work — system design, technical reviews, decision documentation, governance frameworks — does not require timezone overlap. My clients do not experience geographic friction. 🔹 𝐓𝐡𝐫𝐞𝐞 𝐫𝐞𝐜𝐞𝐧𝐭 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐭𝐡𝐚𝐭 𝐜𝐚𝐩𝐭𝐮𝐫𝐞 𝐡𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: 𝐆𝐃𝐂 𝐌𝐞𝐝𝐢𝐚 (𝐈𝐫𝐞𝐥𝐚𝐧𝐝) — built an LLM-assisted database audit engine running across 3 MySQL clusters and 15 production nodes. 13 independent checkers feed findings to the LLM, which grades each as Critical / Major / Minor / Trivial and writes a short, grounded explanation. Runs hands-off 365 times a year. 𝐇𝐑𝐒 𝐆𝐫𝐨𝐮𝐩 (𝐂𝐨𝐥𝐨𝐠𝐧𝐞, 𝐆𝐞𝐫𝐦𝐚𝐧𝐲) — designed and built financial data pipelines on AWS that bridge MS Navision (ERP) and SAP through a single canonical model. Safe to replay, with scheduled reconciliation. 𝐆𝐥𝐚𝐬𝐬𝐰𝐚𝐥𝐥 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 (𝐔𝐊) — Cloud Engineer on the Content Disarm and Reconstruction platform now trusted by NATO and U.S. and U.K. national security agencies. Helped adapt the platform for AWS EKS, Azure AKS, and K3s, and built the file ingress orchestration plugin handling terabytes of potentially infected files. 🧭 𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤 I don't approach projects as feature delivery. I approach them as temporary or ongoing technical ownership — short engagements that clarify direction, longer ones that carry the system through to scale. The shape is the same in both: • Reduce MVP scope while keeping the core value loop intact • Define cloud architecture and system constraints before implementation begins • Make decisions explicit instead of accumulating quiet assumptions • Separate short-term delivery from long-term structural risk • Hand off to in-house engineers cleanly when the moment is right Some engagements take two weeks. Some turn into multi-year work. The goal in both is the same — systems that don't need heroics to keep running. 🎯 𝐖𝐡𝐞𝐫𝐞 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐮𝐬𝐮𝐚𝐥𝐥𝐲 𝐠𝐞𝐭 𝐬𝐭𝐮𝐜𝐤 In early- and growth-stage systems, the biggest problems are rarely about tooling or raw engineering skill. They are decision gaps: • Feature lists that grow faster than clarity • AI is treated as a black box instead of a constrained system • Developers hired before the success criteria are defined • Architectural decisions deferred until they're expensive to reverse • "We'll fix it later" choices that quietly become permanent That's the layer I focus on stabilizing first — so execution stays fast without becoming brittle. ⛁ 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞 𝐚𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞 & 𝐝𝐢𝐚𝐠𝐧𝐨𝐬𝐭𝐢𝐜𝐬 Production databases are where architectural decisions surface most visibly — slow queries, bloated indexes, configuration drift, schema choices that worked at 10K rows and break at 10M. I have extensive hands-on experience with PostgreSQL, MySQL, and MariaDB in high-load production environments. For teams that need a fast, structured assessment: I offer a fixed-price SQL database audit via my Project Catalog — a prioritized diagnostic report delivered in 1–2 days, ranked by business impact. 🧱 𝐒𝐭𝐚𝐜𝐤 • Databases — PostgreSQL, MySQL, MariaDB, OpenSearch, Elasticsearch, DynamoDB • Cloud — AWS, Azure, Kubernetes, Docker, serverless • Security — IAM, encryption, access boundaries, secure data flows • DevOps — CI/CD, GitHub actions, CloudFormation, observability • AI-adjacent — guardrails, confidence gating, deterministic vs. generative boundaries Technology serves decisions, not the other way around. 📅 𝐄𝐧𝐠𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐟𝐨𝐫𝐦𝐚𝐭𝐬 • Long-term architecture and delivery ownership • Fractional CTO or technical advisor • Short-term advisory (1–4 weeks) • Fixed-price SQL database audit (Project Catalog — from $750) Most successful collaborations start small and grow naturally once alignment is in place. 📨 𝐋𝐞𝐭'𝐬 𝐭𝐚𝐥𝐤 If you are unsure what to build, what to cut, or how to de-risk a critical phase — or if your database is showing signs of trouble — a short conversation usually makes sense. From there, we decide together on the right shape of engagement.

Building something complex? I help companies architect, build, and scale systems that actually work — from first commit to 1M users. And I can prove exactly how I do it. Why Clients Hire Me After 74+ Upwork contracts and $200K+ delivered, I've learned that most projects fail for the same reasons: unclear scope, wrong architecture decisions early on, and vendors who say "yes" to everything. I do the opposite — I ask hard questions upfront so we don't discover problems in production. How I Work: AI-Augmented Development I don't just use AI tools — I've systemized them into a Multi-Agent Development Methodology: → Every decision documented and versioned (no tribal knowledge) → Full audit trail — see exactly how your project evolves → Real-time visibility into progress (not just status updates) → Clean handoffs — the next developer won't curse me What I Do → AWS Architecture & Infrastructure — Design, migration, optimization, security → Full-Stack Development — React, Angular, Node.js, Python, Java → Compliance Systems — HIPAA, SOC2, enterprise-grade security → IoT & Real-Time Data — AWS IoT Core, sensor networks, dashboards → Trading & Financial Systems — TradingView, Pine Script, algorithmic strategies Where I Add Most Value → Projects where "getting it right" matters more than "getting it cheap" → Systems that need to scale, comply, or integrate with complex infrastructure → Teams that want a technical partner, not just a code vendor → Rescuing projects that previous developers made a mess of → Teams who value documentation and full visibility The Numbers → 100% Job Success Score → Expert-Vetted status (top 1% of Upwork talent) → $200K+ earned on platform → 50+ developers in my agency for larger engagements → 22+ years building enterprise systems (Hewitt, Xerox, Cognizant) Certifications → AWS Solutions Architect – Professional → AWS Advanced Networking – Specialty → AWS Security, Cloud Economics, and Technical Professional Industries I've Built For Healthcare (HIPAA) · Fintech · SaaS · IoT · Insurance · Logistics · Manufacturing · Legal Tech How to Start Send me a message with: → What you're trying to build or fix → Your timeline → Any constraints I should know about I'll give you an honest assessment — including whether I'm the right fit.
