Software Development Engineer at Mobulous Technologies Pvt Ltd. (2025-07 – 2026-06)

• Solely designed and delivered Amar Krishi — a complex 30+ screen agri-commerce marketplace for the Bangladesh market with 4 distinct user panels (Buyer, Seller, Commission Agent, Quality Control), independently owning the entire mobile codebase from architecture to Play Store deployment.
• Designed and implemented a multi-party negotiation engine enabling buyers and sellers to make counter-offers on each other's posts; commission agents can match deals based on price, quantity, and unit similarity and earn percentage-based or fixed-amount commissions — resulting in a standardized, transparent deal flow that reduced trade resolution time by ~40% vs. manual processes.
• Built a full order lifecycle system — once an offer is accepted, the flow covers truck booking, dispatch management, admin-assigned logistics, buyer payment proof upload, seller invoice generation, and escrow-based fund release; funds held until payment is verified and no disputes are raised.
• Implemented a dispute resolution module where quality control agents review evidence submitted by both parties and resolve conflicts — giving the platform credibility and reducing post-trade disputes by an estimated 30%.
• Engineered real-time negotiation chat using Socket.io with online presence, read receipts, and secure exchange of images, PDFs, DOCX, and XLSX — keeping all trade communication and documentation within the platform.
• Co-developed KonnectX — social media MVP (Feeds, Reels, Stories) with 1 other developer; achieved 40% faster data load via TanStack Query optimisation, directly improving user retention and session duration.
• Led sole R&D and integration of TikTok-level video editing (img.ly + Banuba SDKs) — music overlays, audio mixing, reel/story export pipelines for Android & iOS; delivered on schedule within Agile sprints.
• Introduced and taught juniors to use Reactotron for network and Redux state debugging — standardizing the debugging workflow across the team and cutting issue diagnosis time significantly.
• Mentored junior developers on Haritpane (a farmer service booking app with 12 services) — diagnosed and resolved stale Redux state bugs in the booking flow, resolved architectural queries, and enforced React Native community best practices across the team.
• Conducted regular code reviews and wrote technical explanations for complex integrations; implemented CI/CD pipeline cutting manual release effort by 30% across Android and iOS.

Mobile Application Developer at Zasya Solutions (2023-04 – 2025-05)

• Contributed to an HRM mobile app (iOS & Android) — achieved 25% improvement in attendance accuracy and 30% reduction in manual HR workload, directly saving operational hours for HR teams.
• Configured multi-role access, Firebase push notifications, and iOS/Android build flavors — cut release cycle by 40% and boosted employee productivity by 18%.
• Delivered FIRST LEGO League app (firstlegoleague.sg) for children aged 6–12, 30% ahead of schedule — built dynamic registration forms, QR scanning, and draft saving as part of a small cross-functional team.
• Achieved 80%+ code coverage (Jest + RNTL) and full Detox E2E test suite with debugging & profiling — resulted in a zero-critical-bug production release, reducing post-launch support overhead.
• Contributed to WhitDeals (Flutter/GetX, Play Store) for an Australian client — performance optimisation reduced app load time by 20% and increased user session engagement.
• Participated in Agile/Scrum ceremonies; authored technical documentation for onboarding and conducted code reviews across international client projects.
