I help startups and SaaS teams build fast, scalable web applications. If you're dealing with slow APIs, messy backend code, or need a reliable developer to build things properly from day one — I can help.
🔶SENIOR FULL-STACK SOFTWARE ENGINEER
🔶Experience: 8+ YEARS
🔶SPECIALIZATION:
🔹 Delivering enterprise-grade web applications.
🔹High-performance platforms using the MERN and MEAN stacks (Node.js, React, Angular, Express).
🔹High-concurrency backend development using GOLANG and ELIXIR (PHOENIX).
🔹Data-heavy applications that require flawless performance, real-time capabilities, and microservices architecture.
With advanced capabilities in AI/ML integration and IoT, I ensure your applications are not just functional, but future-proof. I have successfully architected systems handling millions of users, focusing on complex queries, indexing, caching, and rock-solid security.

🔸 Strict Confidentiality:
fully willing to sign an NDA before we begin discussions.
🔸 Total Ownership:
All deliverables, source code, and related assets belong exclusively to you from day one.
🔸 Clean, Maintainable Code:
I adhere strictly to TDD (Test-Driven Development), common design patterns, and industry best practices to ensure your codebase is scalable and easy to maintain long after the project ends.
I am an excellent fit if you lack technical expertise and need a developer who can take full ownership of the architecture, or if you are simply tired of sifting through inexperienced developers and want it done right the first time.
MY DEVELOPMENT PROCESS
To ensure a seamless, stress-free experience, I follow a strict, battle-tested workflow for every project:
1. Architecture & Discovery:
Before writing a single line of code, we define the exact scope, map out the database schema (PostgreSQL/MongoDB), and select the optimal stack (MERN, Golang, or Elixir) tailored strictly to your scalability needs.
2. Agile Execution:
You will never be left in the dark. I provide transparent updates through agile sprints, so you always know exactly what is being built and tested.
3. Robust QA & Automated Testing:
I heavily utilize Test-Driven Development (TDD) and CI/CD pipelines. This ensures every new feature is rigorously tested and deployed without breaking your existing system.
FREQUENTLY ASKED QUESTIONS
🔹Can you rescue or optimize an existing codebase?
Absolutely.
🔹How do we handle timezone differences?
I maintain flexible working hours, deliberately overlapping with your timezone to ensure we have windows for real-time communication.

I build AI-enabled systems for Healthcare Providers, Legal Support Firms, Operations-heavy Businesses, and B2B SaaS teams where workflows are complex, regulated, and have to hold up under real production load.
Not AI demos. Not chatbots bolted onto existing software. Systems where AI is one carefully designed layer inside a reliable, auditable process that actually runs the business.
What I Help You Do:
- Design AI-enabled platforms where the AI is reliable enough to put in front of patients, lawyers, or paying customers
- Ship HIPAA-grade AI systems where PHI never leaks to an LLM, audit logs are append-only at the database level, and BAAs are signed across the full sub-processor chain
- Build legaltech operations platforms with AI document parsing, multi-tenant isolation enforced at the database (PostgreSQL Row Level Security), and AI that never modifies the legal record
- Automate document workflows, intake, triage, dispatch, and internal operations with AI where it has an edge and deterministic code where it doesn’t
- Develop AI-enabled SaaS products from MVP to production-ready platforms with senior architectural judgment, not just code delivery
- Extend AI capability into mobile apps, web platforms, and frontend/backend systems end to end
- Wire AI into no-code and low-code workflows using n8n, Make, GoHighLevel, and Zapier when those tools are the right fit
- Fix and stabilize existing AI systems that are slow, hallucinating, or failing compliance reviews
How I Build AI Systems That Survive Production:
- Most AI projects fail because they focus on the model instead of the workflow around it.
- I design systems where AI is one layer inside a reliable process:
- PHI and sensitive data de-identified before anything reaches an LLM, provable from API logs
- Human-in-the-loop on every AI output that touches a regulated record
- AI used for unstructured-to-structured work; deterministic code for calculation and rule enforcement
- Append-only audit logs enforced at the database permission level, not the application
- Tenant isolation at the database, not the application
- Clear fallback, error handling, and observability from day one
- Every AI call logged, costed, and traceable
This is what separates an AI system that ships from one that survives a HIPAA review, a court challenge, or a security questionnaire from a Fortune 500 procurement team.
What You Get:
- AI architecture that holds up under regulatory scrutiny and senior technical review
- Systems that turn hours of manual work into minutes without losing control
- Clean code your team can maintain, with documentation a senior engineer can read in one sitting
- Senior-level judgment on where AI fits, where it doesn’t, and what to build vs. buy
- Real business impact (time saved, workflows automated, compliance posture strengthened)
Core Stack for AI-Enabled Systems:
AI and orchestration: OpenAI, Claude, RAG pipelines, LangGraph, vector databases (Pinecone, pgvector)
Backend: Python (FastAPI, Django), Node.js
Frontend: Next.js, React, TypeScript, React Native (mobile)
Data: PostgreSQL with Row Level Security and pgcrypto, Redis, APIs, integrations (Stripe, Twilio, CRM systems, EHRs via FHIR R4)
No-code and low-code automation: n8n, Make, GoHighLevel, Zapier
Infrastructure: AWS, GCP, Docker, Vercel, all with BAA-covered configurations for healthcare workloads
Compliance fluency: HIPAA Security Rule (45 CFR §164.308, §164.310, §164.312), HITECH breach notification, FHIR R4, SMART on FHIR, BAA chain management, court-grade evidence handling for legaltech
If you’re trying to put AI inside a real business and you need it to work in production, in regulated environments, at the standard a senior engineering team would actually trust, I can help you design and ship it
