AI Product Architect to Build Production-Grade Financial SaaS End-to-End (AI accelerated)
Laxmikanta is an exceptional developer. He delivered a high-quality web app strictly on time and exceeded my expectations. His communication was seamless, but what impressed me most was his proactivity: he took ownership of the project, anticipating issues and solving them before I even noticed. A true professional and a great asset to any project. Highly recommended!

Stripe API Integration
Lax was brilliant to work with. What I appreciated most; as a project manager, I have to have resources that I can rely to take ownership and execute the workflow with minimal input required from me. Lax met this absolutely perfectly. What impressed me most was that he tested his backend logic by creating a front end mock up so that I could understand the user experience.
If you are a busy project manager and you need a reliable resources that will get the scope completed in-time. Lax is the perfect resource. High quality all the way!

Job Success

One client trusted me for 3 years and $180K in work. That is what it looks like when a founder finds the right engineer, not a vendor, not a ticket executor, but someone who treats your product like their own.
251 Upwork contracts , 100% job success. Expert-Vetted: Upwork's invitation-only top 1%.
I build SaaS products and AI platforms from scratch to production. The results:
popless: Tutor Marketplace: Bookings, Payouts & Sessions
insummary : AI employee engagement for enterprise teams
getrosey: AI document intelligence for compliance review with microsoft and word add in
otio: RAG platform for knowledge workers.
smartbrainskenya: Edtech platform teaching 30K+ students in 100+ schools across kenya and africa.
Each built solo or leading a team of engineers: Architecture, Frontend, Backend, Deployment, and ongoing ownership till production.
What separates me from other senior full-stack engineers: I build using agentic development. Claude Code deployed as specialized agents in parallel: frontend, backend, infrastructure, code review, QA
with E2E testing that mirrors real user journeys. A complete financial platform from zero to production in 4 weeks. Three years maintaining a single SaaS product without a critical failure. This is not how most engineers work.
I operate solo or as technical lead over a team. I step into an existing codebase as well as own a product from the first commit.
AI & AGENTIC SYSTEMS
- RAG pipelines: naive, hybrid, and agentic, with Pinecone and Qdrant , also with pg-vector
- AI agents built with LangGraph and LangChain.
- Multi-model orchestration (OpenAI + Claude).
- Develop MCP servers from scratch or work on existing one.
- Document intelligence platforms. Knowledge graph retrieval with Cognee and GraphRAG.
- LLMs in production: caching, streaming, tool use, MCP, not just API wrappers.
- Claude code expert with agents, skills, commands and use claude cowork for E2E testing to move things as per requirement with Test Driven Development to get to 100% not 80%
FULL-STACK & BACKEND ARCHITECTURE
Next.js App Router, NestJS (Node.js), FastAPI (Python). Multi-tenant SaaS with full tenant isolation. REST and GraphQL APIs. Prisma, Drizzle, or Supabase: whichever the project actually needs.
PostgreSQL at production scale: query optimization, indexing, zero-downtime migrations.
Redis pub/sub, event-driven pipelines. 4+ production platforms on Supabase with 10K–25K active users.
FRONTEND & UI SYSTEMS
Next.js, React, TypeScript, Tailwind, ShadCN. Server components, React Query, Zustand. Real-time dashboards, data-heavy admin panels, customer-facing products: built for the kind of load that exposes shortcuts.
AUTH & ENTERPRISE INTEGRATION
OAuth2, OIDC, SAML 2.0. Microsoft Entra, Google Workspace, Auth0 RBAC, permission-based access control. Enterprise SSO and live data integrations with Microsoft Teams, Jira, and Google Calendar. Built for platforms where a security gap is a liability, not an inconvenience.
PAYMENTS & BILLING
Stripe: subscriptions, metered billing, Stripe Connect for marketplace payouts, webhook-driven flows. Braintree. Built for products where a failed payment or a missed webhook has real business consequences.
INFRASTRUCTURE
AWS (ECS, RDS, S3, CloudFront), Terraform, GitHub Actions CI/CD, Docker. I write the IaC, own the pipelines, own the uptime. GCP, Vercel, Railway where they fit better.
BEST FIT
→ Founders who need one engineer to own the full technical product
→ Teams with a working MVP that needs to survive real traffic and scale
→ Companies adding AI to an existing product: properly, not as a demo that breaks in production
→ Fintech, healthtech, edtech: where reliability is the product
→ Fractional CTO or technical lead for teams that need ownership
Tell me what you are building and the one technical problem that makes it hard. That is where I start.
