★ Featured

Legacy Platform Modernization

Took over a tightly coupled enterprise platform buried in redundant workflows and years of tech debt. Audited every business flow, eliminated 40% of unnecessary processes, redesigned data models and wrote custom migration scripts to move millions of records to the new schema — all with zero downtime and zero business impact.

React Node.js PostgreSQL Migration Azure → AWS
↑ 40% flows eliminated • 70% faster load • Zero-downtime migration • 50% less code

AI Customer Support Agent

Built an intelligent multi-agent system using LLMs and RAG that handles customer queries, routes complex issues to humans, and learns from resolved tickets — reducing average response time by 80%.

OpenAI LangChain Python Pinecone
↑ 80% faster response • 65% tickets auto-resolved

E-Commerce Platform Rebuild

Migrated a legacy monolithic e-commerce system to a modern microservices architecture, improving page load by 60% and reducing deployment time from days to minutes.

React Node.js AWS PostgreSQL
↑ 60% faster load • 95% less deployment time

SaaS Dashboard & Analytics

Built a real-time analytics dashboard for a B2B SaaS product, enabling customers to track KPIs with interactive charts, custom reports and role-based access control.

Next.js Python Redis Docker
↑ 40% increase in user engagement

Workflow Automation Engine

Designed and built an internal automation platform that replaced 12+ manual processes with event-driven workflows, saving 30+ hours per week across the operations team.

Node.js Express MongoDB Azure
↑ 30+ hrs/week saved • 12 processes automated

AI Sales Outreach Agent

Created a multi-agent pipeline that qualifies leads, generates personalized outreach messages, and schedules follow-ups autonomously — integrated with CRM and email.

CrewAI OpenAI n8n PostgreSQL
↑ 3x lead conversion • 20+ hrs/week saved for sales

HealthTech Mobile App

Built a cross-platform mobile app (Android & iOS) for a healthcare startup — appointment booking, telemedicine, prescriptions and push notification reminders.

React Native Node.js Firebase AWS
↑ 50K+ downloads • 4.7★ rating on stores

API Gateway & Microservices

Designed a centralized API gateway with rate limiting, auth and logging for a multi-service architecture — enabling 15 independent services to communicate securely.

NestJS Docker Kubernetes Redis
↑ 15 services unified • 99.9% uptime achieved

Process

A simple, structured framework — not chaos

The goal is to remove ambiguity. Every engagement follows a clear flow, from understanding the business to delivering working software that fits reality.

1

Discover and Decode

Understand the business context, users, constraints and existing systems. No assumptions, only clarity.

2

Blueprint and Architect

Define flows, data, integrations, tech stack and priorities in a simple, readable form that everyone can understand.

3

Build and Integrate

Iterative development, regular demos, and feedback loops with working software, not just documents.

4

Launch, Observe and Evolve

Move to production, track behaviour and performance, and then refine based on real usage, not guesses.

Who I work best with

  • Startups building or refining their first real product
  • SMEs stuck with outdated internal tools and manual workflows
  • Teams needing structure, documentation and technical direction
  • Business owners who want tech to support growth, not block it
  • Companies looking to integrate AI and intelligent agents into their workflows

How I am different

  • Business-first decisions, not framework obsession
  • Clear communication without buzzwords
  • Practical, maintainable solutions over fragile experiments
  • Long-term thinking: scale, security and ownership in mind
