You don't hire a stack. You hire an outcome.
Every engagement is measured by shipped software, faster operations and revenue you can trace back to the build.
Complete web applications from idea to deployment
Modern React dashboards that teams actually use
Secure REST APIs with auth, validation and audit trails
Fast backend systems built for real traffic
Database optimization that cuts query time
AI integrations that automate manual work
ERP and business automation workflows
OCR and document processing pipelines
Cloud deployment with CI/CD pipelines
Bug fixing and long-term maintenance
Performance optimization and cost reduction
Custom software built around your business rules
I turn ambiguous business problems into shipped software.
I'm a Full Stack Software Engineer with 3+ years of experience building enterprise-grade software using Python, React.js, Node.js, FastAPI, Flask, Express.js, SQL, PostgreSQL and cloud technologies.
My work spans enterprise platforms, ERP systems, customer onboarding portals, document processing engines, REST APIs, workflow automation and deep performance optimization — the kind of systems where downtime costs money.
Clients keep working with me because of four things: reliability, clear communication, code quality that survives handover, and delivery on the date I committed to.
"Clean, scalable code isn't a preference — it's the cheapest way to keep a product alive for years."
— How I work
Engineering services priced against business impact
Each service starts with the problem it removes and ends with the result you can report to your stakeholders.
Web Application Development
- Problem
- Ideas stall between design files and a working product.
- Solution
- End-to-end build: architecture, UI, API, database, deployment.
- Outcome
- A live product in weeks, not quarters.
Frontend & React Development
- Problem
- Slow, inconsistent interfaces that users abandon.
- Solution
- Component-driven React with strict TypeScript and design systems.
- Outcome
- Higher activation and fewer support tickets.
Backend & Node.js Systems
- Problem
- Backends that buckle when usage grows.
- Solution
- Service boundaries, caching, queues and observability from day one.
- Outcome
- Predictable performance under real load.
REST API & FastAPI Development
- Problem
- Undocumented, fragile integrations between systems.
- Solution
- Typed, versioned, documented APIs with auth and validation.
- Outcome
- Partners integrate in days instead of weeks.
AI & OpenAI Integrations
- Problem
- Teams doing repetitive judgement work by hand.
- Solution
- LLM pipelines with guardrails, evals and human review steps.
- Outcome
- Hours of manual review removed every week.
OCR & Document Processing
- Problem
- PDFs and scans re-keyed into systems manually.
- Solution
- Extraction pipelines with validation and exception handling.
- Outcome
- Faster processing with far fewer data errors.
Database Design & Optimization
- Problem
- Reports and dashboards that time out.
- Solution
- Schema redesign, indexing strategy, query rewrites.
- Outcome
- Queries that return in milliseconds.
Performance Optimization
- Problem
- Slow pages quietly killing conversion.
- Solution
- Profiling, bundle work, caching and rendering strategy.
- Outcome
- Faster load times and better search rankings.
ERPNext Customization
- Problem
- Off-the-shelf ERP that doesn't match your process.
- Solution
- Custom doctypes, workflows, reports and integrations.
- Outcome
- The ERP fits the business, not the reverse.
Cloud Deployment & DevOps
- Problem
- Risky manual releases nobody wants to run.
- Solution
- CI/CD, environments, monitoring and rollback paths.
- Outcome
- Ship confidently, several times a week.
Python Automation
- Problem
- Spreadsheets and copy-paste running critical operations.
- Solution
- Scheduled scripts, integrations and internal tooling.
- Outcome
- Repetitive work disappears from the team's day.
Bug Fixing, Maintenance & Support
- Problem
- An inherited codebase nobody can safely change.
- Solution
- Audit, stabilise, test and document before extending.
- Outcome
- A codebase you can build on again.
Senior engineering without the agency overhead
You work directly with the person writing the code — no account managers, no handoff loss.
Clean maintainable code
Typed, tested and readable six months later.
Fast delivery
Weekly milestones, no silent months.
Regular communication
Async updates plus a call when it matters.
Scalable architecture
Designed for the next 10x, not just launch.
Mobile responsive UI
Every screen tested from 320px upward.
Secure applications
Auth, validation, least privilege by default.
Modern technologies
Current, well-supported, hire-able stacks.
Long-term support
Maintenance retainers after handover.
Client-first approach
Your deadline and budget drive the plan.
Technologies I build with
A practical, production-ready stack for web apps, APIs, AI integrations and ERP customisation.
A predictable path from call to launch
You always know what's being built this week and what ships next.
Discovery Call
We map the business goal, constraints and success metric.
Requirement Analysis
Scope, risks and a written plan with fixed milestones.
UI/UX Planning
Flows and screens agreed before a line of code is written.
Development
Weekly shippable increments on a staging environment.
Testing
Automated tests, edge cases and performance profiling.
Deployment
CI/CD release, monitoring, and documented handover.
Support
Maintenance, improvements and a guaranteed response window.
Questions clients ask before we start
Small builds ship in 1–2 weeks. A full product typically takes 3–6 weeks. After the discovery call you get a milestone plan with dates before anything is billed.
Yes. Every project includes a support window, and monthly retainers are available for ongoing features, monitoring and fixes.
Often. I start with a short audit, stabilise the risky parts, add tests and documentation, then extend safely from there.
Absolutely. NDAs and contractor agreements are standard for my client work, and I'm happy to use your paperwork.
Python, FastAPI, Flask, Node.js, Express, React, TypeScript, PostgreSQL, MySQL, MongoDB, Redis, Docker, AWS, ERPNext and OpenAI-based AI integrations.
