I’m a Senior AI & Full-Stack Developer with 5+ years of experience building products from idea to scale, from MVPs to production-ready SaaS platforms. I’ve helped launch startups that ranked #1 on Product Hunt and worked closely with YC alumni founders to turn early concepts into scalable systems used by real customers. Most teams bring me in for a feature. But once we step back and look at the architecture, we usually uncover higher-leverage opportunities, automation, workflow redesign, smarter system decisions, often saving six figures annually in operational costs. I don’t just write code. I partner with teams to build products that ship faster, scale cleanly, and actually work long-term.

Senior Backend developer, building Python and Go services for SaaS, healthcare, and AI infrastructure at a Top Rated Plus Upwork agency. 7+ years of senior Backend engineering across Go and Python. Currently Senior Backend Engineer at HTEC, building Go microservices for AT&T's AI chatbot service. Prior: Team Lead on a FHIR-compliant Backend telemedicine platform at Proactive Health Tech (10+ Go services, healthcare data architecture, Python data pipelines). Native English, Bosnian, Croatian. Through Interactivated Solutions, a Top Rated Plus Upwork agency: 38,916 hours, 310+ contracts, 100% Job Success, 200+ public reviews. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⭐⭐⭐⭐⭐"We brought Mesha in as our Backend lead to take over a stalled microservices rebuild. He took the Go services off the previous team's hands, rewrote three of the worst-performing endpoints, and tightened the Python data pipeline that was choking under load. Calm, honest about what wouldn't work, fast on what would. The kind of Backend engineer who actually ships." - Marko T., CTO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most Backend engineers come up through one language and learn the next when forced to. I came up through Go and systems engineering, then layered Python for data pipelines, ML infrastructure, and the cases where Python's ecosystem is the right tool. Senior Backend work where the language choice serves the problem, not the resume. Native English on every standup, every Loom, every Backend code review. Recent Backend work spans enterprise and product builds. At HTEC, senior contributor on AT&T's AI chatbot service - Go Backend microservices, inference routing, and downstream system integration. Prior: Team Lead at Proactive Health Tech, 10+ Go services handling patient records, scheduling, video session orchestration, and HL7/FHIR integration, plus Python pipelines for analytics and reporting. Through Interactivated Solutions, 310+ shipped contracts across SaaS, healthcare, fintech, and AI infrastructure. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I DO ▸ Backend services and microservices - Go (Gin, Fiber, Echo) or Python (FastAPI, Django), REST and gRPC, PostgreSQL data layer. ▸ Backend APIs at production scale - rate-limiting, idempotency, retries, structured logging, observability that survives a 3am incident. ▸ Backend rescues - inheriting a stalled Go or Python codebase, stabilizing services, getting the team back to shippable. ▸ Backend for AI infrastructure - inference routing, model serving, embedding pipelines, vector DB integration, Python data pipelines feeding production ML. ▸ Backend data engineering - Python ETL pipelines, Pandas / Polars, async workers, batch and stream processing, Go for high-throughput hot paths. ▸ Backend team leadership - I lead Backend teams of 3-5 engineers, code-review heavy, CI gates that catch the drift juniors miss. ▸ Backend performance work - query tuning, service profiling, infrastructure right-sizing, real load testing on real data. ▸ Full stack developer and software developer foundations - front end experience with React and Node.js, web developer capabilities for full-cycle delivery. ▸ Adjacent stack: Docker, Kubernetes, Terraform, AWS, GCP, Redis, Kafka, PostgreSQL, OpenAI and Anthropic API integration. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK Every Backend engagement starts with a discovery pass on the existing codebase before a line of code changes. Service boundaries, data flow, and observability gaps mapped upfront. Async with daily updates, Claude Code and AI tooling to move faster without compromising stability. Documented handoff so the Backend is maintainable after the engagement ends. MY PROCESS ▸ Day 1-3: Backend discovery on the Go or Python codebase, identifying load-bearing trade-offs. ▸ Week 1: stable Backend services, branch hygiene, CI gates, observability baseline. ▸ Weeks 2-4: Backend feature shipping in two-week iterations. Code review before merge. ▸ Continuous: working code in your repo end of day. You own the Backend codebase and every architecture decision is yours to question. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Already have a project in mind? Send me a message - no brief needed. I will help map out the scope and see what is possible before committing to anything.
